Restoration of failing single teeth in compromised anterior sites with immediate or delayed implant placement combined with socket preservation--a report of two cases.

Restoring failing anterior teeth with a dental implant restoration when there is significant damage to the bone, soft tissues, or both presents a difficult clinical challenge. The goal is to produce a result in which the soft tissue contours, papillae, and in particular the labial soft tissues remain stable over time. While a number of techniques have been utilized, socket preservation and socket seal in combination with immediate or delayed implant placement can be a valuable protocol. The use of this technique is illustrated in two challenging cases of patients with high lip lines.
